Question

In science class, Logan estimates the volume of a sample to be 42 mL. The actual volume of the sample is 38 mL. Find the percent error of Logan’s estimate. Round your answer to the nearest tenth.

Answer 1

10.5%

Explanation:

`\text{Percent (\%) Error}=\frac{|\text{Actual-Estimate}|}{\text{Actual}}*100\%=(|38-42|)/(38)*100\%\approx10.5\%`

Therefore, the percent error of Logan's estimate is about 10.5%
